APPARATUS FOR HEATING WATER.

SPECIFICATION forming part of Letters Patent No. 482,076, datedSeptember 6, 1892.

Application filed April 1 1892. Serial No. 427,348. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY B. CLARKE, a citizen of the United States,residing at Chicage, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Apparatus for Heating Water, ofwhich the following is a specification.

My invention relates to apparatus for heating water, and has for itsobject to provide convenient means for furnishing water of a highertemperature than that ordinarily used in barns and other such places.

It is illustrated in the accompanying draw ing, wherein- A is the baseof an ordinary stove, B the drum thereon, and C the pipe therefrom.

D is the floor, above or upon which rests the tank E. From this tank thepipe F, controlled by the valve F, leads down to the pipe F and thispipe leads into the coil F in the drum B, and thence the pipe F leads tothe coil F in the stove proper. From this latter coil leads the pipe Fback to the tank E. The pipe F is provided with the valve G and opensinto the pipe H, and the pipe F connects with the short pipe J, whichhas the controlling-valve J, and terminates in the connection J The pipeH is also connected with the main or supply pipe K, which is providedwith the valve K, and also terminates in the connection J L is asafety-pipe leading from the top of the tank E and provided with thevalve M and the safety device N. These several connections might besomewhat altered and the arrangement and proportion of the parts bechanged without departing from the spirit of my invention.

0 is a valve in the pipe F The use and operation of my invention is asfollows: The main water-pipe K is connected with the usual source ofsupply and a current is admitted, the same passing in the directionindicated by the arrows into the tank E, where it is stored. By openingthe valve F in the pipe F and the valve Jin the pipe J the water will bepermitted to flow downwardly through and fill the coils in the stove anddrum, and then pass outwardly through the connection and into whateverpipe maybe associated with the connection J The coils will of coursefill if no discharge of water is made through the valve J by reason ofthe presence of the pipes F and F If the stove is provided with fire, itis evident that there will be a continuous circulation of water throughits coils, for the cold water entering through the coils will graduallysettle through them, and the hot water will pass upwardly through thepipes F and F If this Water should be too warm when discharged, it maybetempered by mixing therewith a quantity of water by opening the valveK. The circulation through the coils may be stopped, when desired, byclosing the valve 0 or by closing the valve F. By closing the valve Kand G and opening the valves F, O, and J the water to be used may betaken from the tank with little or no circulation through the coils. Thesafety-pipe L and safety device will prevent danger from overpressureincident to heating of the water.

I claim- The combination of an elevated storagetank, a lower heatingapparatus containing a coil, a pipe F,leading from the top of the coilto the bottom of the tank, a pipe F, leading from the tank to the bottomof the coil, a supply-pipe K H, leading to the tank and discharging atthe bottom thereof, a cross-pipe extending from the supply-pipe to thepipe which leads from the top of the coil to the bottom of the tank, andpipes communicating with the lower end of the pipe which leads from thetank to the bottom of the coil and with the feed-pipe, respectively, andterminating in an outlet-tube J the said pipes being provided withsuitable valves whereby the circulation through the coil may be stoppedor controlled.
